摘要
某铁矿西矿区因地压活动造成巷道变形破坏较为严重,影响矿山的安全生产。经现场调查矿山地压显现特征,分析了地压产生的机理,找出主要原因,提出针对性的四项综合治理措施,实施后取得较好的效果,恢复了矿区正常的安全生产。
West mining area of Lizhu Iron Ore is damaged severely for tunnel deformation due to ground pressure activity, impacting the safe production of the mine. Through the on-site survey for appearance characteristics of ground pressure of mine, it analyzes the mechanism of the occurance of ground pressure and finds the main reasons. It puts forward for comprehensive treatment measures. After the implementation, it achieves good effect, and recovers the normal safe production of the mine.
